Tessel, created by David Letellier & Lab[au], is basically a giant robotic kaleidoscope suspended from the ceiling. In all, it’s made of 40 separate mirrors, which join to form a 13’x6.5′ expanse. (These were created using tiling software — similar to the software engines that computer animators use to create polygonal wireframes.)

The moving mirrors respond to the sounds by changing configuration, and what results is aural, kinetic piece of sculpture:
